Question

the perimeters of two squares are 40cm and 32cm. find the perimeter of the third square whose area is equal to the difference of the areas of the two squares.​

Answer 1

Answer:

We know perimeter of square = 4(side)

So Side of first square = 40/4 = 10 cm

Side of second square = 32/4 = 8 cm

Area of third Square = 10*10 - 8*8

= 36 cm

So side of third square = 6 [because area of square = side*side]

Perimeter = 4*Side = 4*6 = 24 cm
